Pavement construction method with inspection well

Abstract

The invention relates to a pavement construction method with an inspection well. The pavement construction method comprises the following steps of 1, excavating a trench according to design requirements, performing pipeline installation and conducting backfill compaction; 2, constructing a well body of the inspection well; 3, conducting backfilling on the periphery of the well body, and conductinglayered compaction on backfill through an upright tamping machine; 4, laying a road base layer and a pavement base layer; 5, excavating the parts, located on the well periphery, of the road base layer and the pavement base layer, forming a containing groove in the well periphery, placing well ring rebars in the containing groove, conducting concrete pouring on the well ring rebars, and forming awell ring of a cast-in-place reinforced concrete structure; and 6, conducting pavement asphalt construction, and installing a well cover. The pavement construction method can effectively improve the degree of compaction of the filler around the inspection well and reduce the settlement condition of the surrounding area of the inspection well.

Description

Technical field [0001] The invention relates to the technical field of road construction, in particular to a road construction method with an inspection well. Background technique [0002] Inspection wells are provided for the maintenance of power supply, water supply, drainage, sewage, communications, cable TV, gas pipes, street light lines, etc. of the urban underground infrastructure. They are generally installed at pipeline junctions, turns, pipe diameters or slopes. The changes and the regular intervals on the straight pipe section are convenient for regular inspection of the attached structures. [0003] During construction, pipelines are generally laid first, inspection wells are built, and then trenches are backfilled for road construction. Filling materials around the inspection wells are filled with dry sand. Because of the existence of inspection wells, large-scale rolling equipment is stressed. The impact of the actual work makes the packing material around the inspect...

AI Technical Summary

Problems solved by technology

[0003] During construction, the pipeline is usually laid first, the inspection well is built, and then the trench is backfilled for road construction. The surrounding of the inspection well is backfilled with filler, which is dry sand. Because of the existence of the inspection well, the pressure on large rolling equipment Influenced by the actual work, the degree of compaction of the filling material around the inspection well is not enough

After opening to traffic, because the compaction degree around the inspection well is less than that of other areas of the road, the settlement of the area around the inspection well is greater than that of other areas of the road, making the road uneven and easily damaged, which brings inconvenience and safety to people's travel Hidden danger
